Original application fled October 20, 1920, Serial ms. 414,551. Divided and this application filed Februcry 7, 1921. Serial No. 442,975.

citizen of the United States, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Im rovements in Disk Wheels; and I do here by declare the followin to be a full, clear, and exact descri tion o the as will enable ot ers skilled in the art to which it appertains to make and use the same.

present invention relates to disk wheels that are-equipped with pneumatic tires and has for its object'to provide an extremely simple.and highly eflicient means for afi'ordin read access to thevalve stem of the tire, om t e outer side of the wheel, where the valve stem is :on the inner side of the wheel disk. The present application is. filed as a division of m pending applictober 4, 1920.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings Figure 1 is a side elevation of the tireequipped disk wheel equipped in accordance with my invention, said wheel, as illustrated, being of the single disk type;

Fig. 2 is a vertical section taken on the line 2-2 of Fi 1, some parts being in full;

Fig. 31 is a re. mentary view looking at the inner side 0 the disk and showing a port cover in a port-closing'position;

Fig. 4 is a section on the line 4-4 of Fig. 3; and V Fig. 5 is an elevation looking at the outer face of the detached port cover.

The numeral 6 indicates the flanged wheel hub; the numeral 7, the wheel disk; the numeral 8, the w'heelrim; the numeral 9, the tire casing; and, the numeral 10, the inner tube, which latter has the customary valve stem ll projected radially inward through the rim 8 and the flange of the disk 7.

In the construction illustrated, the disk is provided with a charging port or passage 12 shown as round and located, approximately in line with the end of the .valve stem 11. This port 12 is normally closed by a round cover plate 13 that fits said port and is adapted to beseated against a flange or like portion 14 pressed inward from the disk at the margin of said port.

In this arrangement, the .cover plate 13 is arranged to be moved from its port-closing osition by first drawing the same outwar and then swinging the same toward one side of the port. To thus support said cover plate, I provide an arm 15 which is pivotally connected to the wheel disk at its inner side at 16. At itsfreev end, the arm 15 is loosely jointed to a small bolt 17, the threaded outer end oi which is extended through an axial perforation 18 in the cover plate 13 and is provided with a thumb nut 19, or the like. T o prevent accidental ro-, tation of the nut 19, the cover plate 13 is shown as provided with a slightly depressed rectangular seat 20 in which the rectangular ortion of the nut 19 is normally seated.

ith this construction, the cover plate 13 may be one side so as to about half open' the art 12 without removing said cover plate f i'om the bolt 17. Hence, thetport 12 should be made lar e enough to permit the tube to e connected to the. valve stem through the opening afforded by said port when but half open. However, if the nut 19 be removed, the port-closingplate may be entirely displaced fronrsaid port and, in that event, said port may be made smaller. Thisdevice is especially adapted for application to a single nevertheless, be a plied to the outer disk of a double disk w eel. Said device is very simple, easily operated and eflicient for the purpose had in view. It allords convenient means for reaching-a valve stem that is 10-. cated on the inner side of a wheel disk.

Preferably and as shown, the arm 15 is made of fiat spring steel, but, of course, it might be a more rigid or even an unyielding element.

What I claim is:

1.. A disk wheel having in its disk a ort through which the valve stem of an app ied tire may be greached, a displaceable cover for said port mounted for outward opening movement, and an arm applied to the inner side of said disk, connected to said cover and normally holding the same in port-closing position.
